You'll think you're in hog heaven after riding around on what you have now. You may not want to get off it, or have your neighbors get mad cause you went over and cut their lawn too.

Ill admit, its way more than what I want to spend, but since I work on my own equipment, I am just now purging all of my 'junk'. My philosophy is 'you get what you pay for' and im willing to pay more for reliable, quality equipment.

Does anyone know what the deal is on the engines for the Z720A? the 2010 have a 25HP, the 2012/13 have a 22.5 and then the new Z915B has a 24.5 or something. However, I am under the impression that the motors are all exactly the same. Did the government change the HP calculations or what?

After the small engine manu's got sued a few years ago for over rating their engines, Kawi started rating them more accurately, and Kohler is slowly following their lead. B&S is still way behind and using over inflated numbers. The engines are all the exact same as they always were, and produce the same power.

BTW- that 25 Kohler is labeled at 22.5 by some sources, byt the stickers on the Deere engines says 21.9 Regardless, it'll do the job.

That's OK. Every teenage male does the same thing with his car.

Got my mower yesterday. Its a beast! It cuts really nice and does a great job. One thing I wanted to ask about the the whine when you turn or move. I assume its from the transmission pumps/motors. When at full throttle, you don't notice it as much. At low speeds, its loud and you can feel it. I assume this is normal. The left one is much louder than the right. I think I remember hearing this type of noise from hydrostatic type equipment, but wanted to check.

Yes, that is normal hydro whine. There are a ton of youtube videos in which you can hear a ZTR doing that. Even hydro drive utility tractors do that. However, keep an eye/ear on them. They should have the same sound. Are you hearing it louder on the left with the deck on, or off? If the left is louder to you while the deck isn't running, that may be something to have the dealer check out eventually if it doesn't seem to go away once you get some hours on the machine. If it is louder on the left with the deck on, it's usually because the air coming out of the discharge chute drowns out some of the whine.

BTW-
The 720 comes with std lift blades. try some OEM high lifts that come on the 900 series, or better yet, some Oregon Gator G6's. they really work well under that deck on that machine. They are what I ran almost always when I owned mine.

I just mean when I move the right stick, the whine is there, but not quite as loud as when I do the same thing with the left stick. This is when the deck is not running. When at full throttle, its not as pronounced, when the deck is running, you can't hear it at all. Im unfamiliar with the machine, but it cuts 12" grass without any problem at all. Seriously...its awesome.

Like I said, they all do it. I'm glad you like it. I've told others it will handle tall grass well, but some have questioned my integrity for saying so. While you were posting, I was typing an edit to my last post. Read it.

Thanks for the tip on the blades. I may try those after these are ready for replacement. I didnt run it full speed, it goes WAY faster than I would ever need to mow, but with the speed I ran, it cut grass like crazy. Im going to bush hog the rest of the tall grass so I can find the hidden logs or sticks, but after that, the JD will handle it without tearing it up.
